What app have you been using?
The best on by far is Nordic's Master Control Panel. It's really good. Only available on Android though. I don't think there are any good ones for iOS.
Isn't it time for uncompressed A2DP audio at last? It would solve both quality (generation loss) and latency issues.
aptX already allows high-quality audio streaming over BT and has both a lossless and a low-latency mode. Device support is also already here, I saw a few last time I was in an electronics store.
I've been really fascinated recently by whipping out my smartphone in public and using a Bluetooth LE explorer app to look at what's being advertised, and it's brilliant. We are all constantly surrounded by devices which are screaming data about themselves everywhere they go. Bluetooth 5 seems to increase the range of LE communications, but since I'm almost sure we're going to have some horrible public hack of one of…
> We are all constantly surrounded by devices which are screaming data about themselves everywhere they go. Perhaps you would like to explain what the problem with this is? Broadcasting presence in itself is not a security hole - unless you think "Do not broadcast SSID" is a WiFi AP security feature (it's not). If WiFi can be secured (with devices that "scream data about themselves"), why would Bluetooth be any diffe…
I suspect the GP is just referring to the stuff they happen to be transmitting in the clear right now because they weren't thinking about the risks. Basically like early days 802.11 when you needed to pay big money for something like wireshark.

What will it take for wireless keyboards and mice to use Bluetooth? Most ship with their own custom dongle. A single port MacBook, for example, doesn't really make sense until Bluetooth devices become more popular.
Seems to be getting better though; a quick look at the local price comparison site gave 419 wireless keyboards, 296 of which are using Bluetooth.
Tongue-in-cheek, well mostly but not entirely .. I do appreciate e.g. accurate travel times, yet refuse to believe they won't take it to the next step. http://www.theage.com.au/victoria/how-vicroads-tracks-your-e...

Well, there are a couple of reasons I think this is different:
1. APs are static and not mobile, versus Bluetooth devices – which can move, and are more importantly personally associated with a person. That inherently provides opportunities for more leakage on information, since device addresses can now be used to track people.
2. Devices aren't just advertising their existence. They're also advertising their services, and in some cases actually just sending whatever data a client asks for. There's a particular brand of iPad stylus which seems to just open up and send it's accelerometer readings to any device which connects. There seem to be heart-rate monitors that do the same.
For me, it's much more worrying that devices happily broadcast personal information without authentication – I don't actually think device advertisement is a big deal in comparison!

I have no idea if it's particularly good in comparison to others, but I downloaded it to debug a Bluetooth LE device I was building and it was a pretty straightforward UI.

> We are all constantly surrounded by devices which are screaming data about themselves everywhere they go. It's also terrible that people, and their clothing, are so detectable in the visible light spectrum. Where's the 'tarnkappe' when you need it? ( https://en.wikipedia.org/wiki/Cloak_of_invisibility ) Also appreciate the "will be marketed as 'Bluetooth 5.' [no dot zero]". Sounds like a band name, or a gang. Good…
I wasn't completely clear above, but there are a couple of differences:
- Your clothing doesn't contain unique identifiers (yet!) :)
- The devices seem to often be happy to broadcast their information in the clear. Your clothes don't advertise your position or heart rate to the whole world either!
